This modest, paper-bound book gives an informal summary of the methods used at the National Public Dispensary for Digestive Diseases in the medical and surgical treatment of all varieties of gastrointestinal disorders. Although it lacks an alphabetical index and attempts no critical appraisal of fundamental assumptions or statistical evaluation of results, the book is interesting as a readable account of prevailing theory and practice, for each of its eighteen chapters is written by a different specialist and numerous prescriptions are given, both medical and dietary.
